My black cuke has started to spit/crap out thin white strands up to 12 inches long at a time. I find them strung out accross my rock and the sand. Didn't know what they were until I actually caught him doing it
When I fish them out of the tank they are so sticky and strong they would make Spiderman proud
He doesn't seem the worse for wear by doing it but any ideas as to just what the hell he's doing would be great
